EM12c: How to recover EM(OMS) to its original wallet and cert after messing up with 3rd party wallet and certificate?

Problem: I was trying to secure OMS using 3rd party wallet. Created a certificate request. Secured OMS and console using this wallet and certificate successfully. But then while trying to start oms, it did not come up and always showing javax.net.ssl.SSLHandshakeException in emctl.log:

ERROR oms.StatusOMSCmd processStatusOMS.309 - Received fatal alert: handshake_failure

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

I did figure out that there is a potential issue with certificate/wallet that I generated. It’s not valid. So I wanted to bring oms back to its original configuration with its wallet and certificate.

Solution: Using following commands, I was able to bring up the OMS without any issues.

%emctl stop oms

%emctl secure oms

%emctl secure console -self_signed

%emctl stop oms -all

%emctl start oms
